The FBI is investigating after Los Angeles-based painter Emma Webster revealed she was conned by a scammer pretending to be Lady Gaga.

The artist was so convinced she had a new celebrity fan she even agreed to sell her work at a discount - only to see it come up for auction three years later when she was told by Gaga's management she had been "duped" and the singer had never bought it.

The painting - a large landscape called Happy Valley - had been sent to Christie's for sale by Hong Kong gallerist Matt Chung who told the New York Times he bought it in good faith and "was also a victim of the unfortunate circumstances".

Christie's is now holding on to the painting while Webster and Chung try to agree what to do next.

Someone has to stand up for selfies - so step forward Tate Britain boss Alex Farquharson.

The director of the London gallery spoke out after his counterpart in Florence’s Uffizi Gallery, Simone Verde, pledged to set "very precise limits" on people "who make memes or take selfies for social media" after a visitor tore a hole in an 18th-century portrait while posing for a picture.

Farquharson told the Sunday Times he wanted people to snap away at the collection, which includes work by David Hockney, Bridget Riley and J.M.W. Turner, saying the rise of social media had made "everyone a curator".

His stance is in contrast to similar institutions including the Prado in Madrid and New York’s Frick Collection which already ban visitors from taking pictures with their phones.

But even his laissez-faire approach has its limits and he draws the line at selfie sticks, saying: "We don’t want people’s eyes being taken out — or the artworks".

A man at the center of a long-running art forgery case has pleaded guilty to orchestrating the sale of hundreds of fake works attributed to Indigenous Canadian artist Norval Morrisseau.

James White pleaded guilty at Ontario Superior Court to creating fake documents and trafficking 502 forged artworks, but investigators suspect there are thousands of fake Morrisseaus around the world with many of their owners not suspecting they bought a forgery.

White will be sentenced in August with several of his collaborators already serving jail sentences having pleaded guilty to other charges.

Morrisseau is regarded as the founding father of contemporary Indigenous art in Canada, but police estimate there could be as many as 6,000 fake works in circulation having been sold for tens of millions of dollars.

American artist June Leaf steps out of the shadow of her photographer husband Robert Frank in a major new retrospective of her career.

More than 150 works made over 75 years, from paintings to prints and sculptures, are on show at the Addison Gallery of American Art in Andover, Massachusetts, before moving to New York's Grey Art Museum in September.

Co-curator Allison Kemmerer said the show was a "long-overdue" examination of the career of Leaf, who died last year, describing her as "one of the boldest and most adventurous artists of her generation".

The Director of the Louvre is casting her net far and wide to find philanthropists to help pay for the Paris museum's $316 million makeover.

Laurence des Cars told French newspaper Le Monde she had just returned from Japan and Singapore with "some promising prospects" and she also expected support from "major American philanthropists" as well as public and private backing in France.

How the money will be spent will become clearer this October when a 21-strong international jury produces a shortlist of five designs before a winner is announced early next year.

The Louvre has millions of visitors every year, with many of them waiting in line for a glimpse of Leonardo da Vinci's Mona Lisa, and has become a victim of its own success with complaints about overcrowding and a creaking infrastructure but des Cars told the newspaper she hoped the winning design would give the museum "some breathing room".

There is no art hanging in the new Geffen Galleries at the Los Angeles County Museum of Art (LACMA) yet, but it has had its first visitors with previews for press and public alike inside the $720 million building.

Among them was Los Angeles Times art critic Christopher Knight who told his readers they would have "never seen so much concrete in one place", saying it made the gallery's 90 rooms and long corridors "monotonous".

He also cast doubt on the "cumbersome" and "expensive" process of hanging and re-hanging work on plain concrete walls, but at least he liked the windows saying the views of the city were a "welcome relief".

Writing in The Guardian, Lois Beckett quoted museum CEO Michael Govan who said it would present work in a "non-hierarchical" way rather than organized by period or geography, an approach she said made the layout "unpredictable and confusing to navigate".

Even Govan admitted "the building has been an issue", telling the New York Times the purpose of the previews was to "take that out of play, so when it opens everyone can focus on the art".

The building, named after music industry titan David Geffen who personally donated $150 million to the project, is set to open next April.

1 - The anonymous artists who placed an eight-foot-tall golden monument of President Donald Trump in Washington D.C. have returned with another satirical work - a gold-painted TV set. The video installation, placed on the National Mall, played a silent, 15-second loop of Trump dancing against different backdrops.

2 - She may be on her way out of Vogue but the veteran fashion magazine editor Anna Wintour will reportedly stay in charge of the Met Gala. Under her stewardship, the New York Metropolitan Museum of Art’s annual fundraiser for its Costume Institute has become one of the most important events in the fashion industry, raising $31 million this year alone.

3 - The Manchester Museum in the North of England is asking visitors to vote on whether it continues to display the remains of an Ancient Egyptian woman. The body of Asru, a woman who lived in Thebes around 2,700 years ago, has regularly been on display in her decorated wooden coffin for 200 years.
